Corsica is an island economy marked by the complete absence of any of the big holdings and multinationals that fuel and forge the worldwide economy. Equally absent is any of the kind of medium-sized enterprises servicing big business that have spearheaded local economies in other regions like Lombardy. Corsica's economic fabric is essentially made up of small and home businesses, farm smallholdings, artisans, and small-scale retail. Given how public-sector capital investment is already hypertrophied, a policy of investment in human capital could be a compelling new opportunity to trigger a dynamic regional development impetus. Leading the way, the University Institute of Technology Corsica, Corsica University's affiliated school of applied vocational technologies, is demonstrating its ability to act as a structurally engaged facilitator of island-wide spatial planning and regional branding. As a founding pillar in pioneering the emergence of a sandwich-course training system in higher education in Corsica, in 2010 the university made its entire training curriculum fully accessible to all through the signature of apprenticeship training or vocational qualifications agreements. This grass-roots programme is the outcome of a committed core strategy to develop partnerships with the island's key social and economic communities (businesses, community groups, and local authorities), and it plays a fundamental role in shaping and selling the most vital valued assets that typify a regional territory emerging into a structured destination-brand identity (simultaneous growth in the employability and quality of school-to-work transition shown by its human capital, mass shift in the degree of skill acquisition directly tied to the regional territory's own organic needs, fluidity of knowledge transfer fully controlled through sandwich placements, deep sustainable entrepreneurship education etc.). After highlighting the specific features of the sandwich training policy development process in Corsica as a shaper of the Regional Vocational Development Programme, this paper brings an analysis of the lessons learned from the pioneering example of the University Institute of Technology Corsica as a dynamic engineer of structured future and regional brand for Corsica.  相似文献

The transition process in Central and Eastern Europe was associated with growing environmental awareness. This paper analyses the determinants of pollution abatement and control expenditure at plant level in the case of Romania using survey data and a multilevel regression model. Our findings suggest that, although Romania has improved its environmental performance, formal and informal regulations are still only partially developed owing to the difficulties of economic transition, and heterogeneity across regions remains considerable.  相似文献

Advertising remains one of the most popular marketing instruments, and many studies have studied its sales effectiveness. However, prior research has either looked at the total spending of a brand/firm, or has focused on the most popular media, especially TV advertising. Even though huge amounts are also spent on “smaller” media such as billboards and cinema, little is known on their effectiveness.  相似文献

Opening, lunch and closing of financial markets induce a periodic component in the volatility of high-frequency returns. We show that price jumps cause a large bias in the classical periodicity estimators and propose robust alternatives. We find that accounting for periodicity greatly improves the accuracy of intraday jump detection methods. It increases the power to detect the relatively small jumps occurring at times for which volatility is periodically low and reduces the number of spurious jump detections at times of periodically high volatility. We use the series of detected jumps to estimate robustly the long memory parameter of the squared EUR/USD, GBP/USD and YEN/USD returns.  相似文献

Dynamic Programming is used to derive the optimal feedback solution to the minimization of a quadratic welfare loss-functional subject to a linear econometric model, when the value of some instrument variables can not be optimized in every model period, but only in single ones. In this way, the relative inertia of fiscal policy-making, as compared to monetary policy-making, can e.g. be taken into account. Analytical expressions are derived for the optimal feedback rules and for the minimum expected losses, and iterative schemes are proposed for their numerical computation. It is suggested that a numerical analysis of the economic gain to be realized by making more frequent adjustment of fiscal policy variables than is actually undertaken could yield valuable information for policy-makers.  相似文献
